        <p>
      <span class="emphasis"><em>delayw</em></span> writes <span class="emphasis"><em>asig</em></span> into the delay area established by the preceding <a class="link" href="delayr.html" title="delayr"><em class="citetitle">delayr</em></a> unit. Viewed as a pair, these two units permit the formation of modified feedback loops, etc. However, there is a lower bound on the value of <span class="emphasis"><em>idlt</em></span>, which must be at least 1 control period (or 1/<span class="emphasis"><em>kr</em></span>).
